FLASHING PLUG.

Application filed January 25, 1924. Serial No. 688,580.

To all whom it may concern Be it known that I, CHARLES OLoF J0- HANsoN,a citizen of the United States, and a resident of Tucson, in the countyof Pima and State of Arizona, have invented new and Improved FlashingPlugs, of which the following is a full, clear, and exact description.

This invention relates to improvements in flashing for roofconstructions, and has par ticular reference to a plug for retaining theflashing in position.

An object of the invention is to provide an improved plug of simple andinexpensive construction, which is capable of being easily and quicklysecured in position and which will be effective in retaining theflashing in place.

The above and other objects will appear more clearly from the followingdetailed description when taken in connection with the accompanyingdrawing, which illustrates a preferred embodiment of the inventive idea.

In the drawing- Figure 1 is a fragmentary section through a wall showingthe invention in its operative position;

Figure 2 is a front elevation; and

Figure 3 is a plan view of a blank in which the plug is formed.

In the construction of roofs for buildings and other like structures itis customary to extend a layer of composition material upwardly from theroof proper along copings, walls, chimneys and other portions of thebuildin projecting above the roof to form a weather-proofing cover forsaid walls, copings and the like. The usual flashing is then placed inposition in overlapping re lation with respect to the part of thecomposition material engaging the wall or coping to form a cover forsaid part in order to exclude moisture from gaining access between thematerial and the wall. Thus in building a wall or coping, which is shownin the drawing as formed of a plurality of bricks 4 with interposedlayers of mortar or cement 5, the flashing 6 is engaged with the surfaceof the wall and the portion 7 thereof extended inwardly upon the uppersurface of the lowerbrick 4, after which the layer of mortar is spreadover: the brick and the upper brick placed in position. After the mortarhas been permitted to properly set the plug or retaining element of thepresent invention is driven into the layer of mortar in such a manner asto en gage the flashing 6 and securely maintain the same in properposition.

The plug is shown in its preferred form as being made from a singleblank of suit able material, such as sheet metal of triangularformation, as shown in Figure 3. The blank is cut longitudinally, asindicated at 8, along a medial line extending at right angles from theshort side of the blank to a distance of approximately one quarter ofthe length of said blank, the remaining portion of the blank, which forex pediency is termed the body portion, is then bent along the line 9which extends coincident with the cut 8 to the pointed end of the blankto form the angularly disposed sections 10 which combine to provide abody portion of tapered formation which Will facilitate the entry of theplug into the layer of mortar. At the inner end of the cut 8 the blankis folded along the transverse lines 11 to form the flanges 12 extendingat right angles to the body portion of the plug. "When said body portionis bent to provide the angular sections 10 the flanges 12 will bedisposed in overlapping relation with respect to each other, as bestillustrated in Figure 2. The double thick ness of the flanges 12 thusprovides a reinforced driving head for the plug which will adequatelyresist force of a hammer head or other like implement to preventdistortion of the plug when the same is being driven into-the positionshown in Figure 1. When secured in this position a portion of the freeedges of the sections 10 will engage the inwardly extending portion 7 ofthe flashing while the inner flange 12 will abut against that portion ofthe flashing 6 which engages the outer surface of the wall or copingwith the outer extremities of the sections 10 extending slightly beyondsaid outer surface to provide an inclined water shed which will minimizethe possibility of moisture seeping into the layer of mortar and gettingbeneath the flashing.

What is claimed is:

1. A flashing plug including a body of tapered formation bent to provideangularly disposed complemental sections capable of insertion into awall to engage the free edges of said sections with a flashing,

and overlapping flanges at one end of said body forming a' [driving headtherefor.

2. A flashing plug including a body bent to provide itIlgLllitl'lydisposed sections of tapered formation and presenting free edges forengagement with a flashing, eachOf said sections having an angularlydisposed flange at its larger end arranged 'in'overlapping relation withrespeqt to the flange 10 of the other section to form 2 driving head.

3. A flashing plug formed from a single sheet of material of ltri ang ularifomnation bent along a longitudinal medial line to overlappingflanges forming a driving head $01 the plug- GHABLES OLOF J HANSON.
